Multisig from a nano wallet and android wallet

i added my brother as a cosigner from my android wallet …using his public key

next my wallet get locked cant send any transaction …i guess my account became a multisig account.with 1 cosigner which is my bro

my brother uses a nano wallet since nothing showed up in his wallet
no notification no + sign no options like in the Tuto of the standalone wallet

he doesn’t know how to control the multi sing account to initiate transactions…

we are stuck … now i want just to come back and unlock my wallet

please help

You made a 1-of-1 multisig account with your brother being the only signer over your account.

Once an account is multisigged, it is no longer can initiate txs on its own. Only cosigners can start a tx. In this case, it is only your brother.

I suggest maybe a 2-of-3 contract over your account. one on your mobile, one on your brother’s mobile, and one on your desktop with a NanoWallet passphrase wallet. And always PLEASE back up your private keys.

if on a mobile wallet, he can select new tx and then select your account from a dropdown. since he is 1-of-1 the tx will instantly go through.

if on NanoWallet, he can choose the multisig option in the send panel.
